Base-flipping dynamics in a DNA hairpin processing reaction

Abstract:

Many enzymes that repair or modify bases in double-stranded DNA gain access to their substrates by base flipping. Although crystal structures provide stunning snap shots, biochemical approaches addressing the dynamics have proven difficult, particularly in complicated multi-step reactions. Here, we use protein-DNA crosslinking and potassium permanganate reactivity to explore the base-flipping step in tN5 transposition. We present a model to suggest that base flipping is driven by a combinatio...
